Re: [Tinycc-devel] wrong/incorrect result of sizeof

[James Lyon]

It's impossible to answer this question without knowing the target 
platform. The C standard doesn't specify this stuff but it is usually 
specified by an ABI (application binary interface) so that code produced 
by different C compilers interoperates correctly. On Linux-x86_64, both 
gcc and tcc give 16 for this program.
